实例化所有从xml序列化的类对象

Question

我已经将XML文件反序列化为一个使我的soap请求成为对象的类。当我序列化C＃类时，大多数类对象未填充输出xml文件。

示例

GetUserReq.Envelope getUser = new GetUserReq.Envelope();
getUserResponse = new GetUserRes.Envelope();
getUser.Body = new GetUserReq.Body();
getUser.Body.GetUser = new GetUserReq.GetUser();
getUser.Body.GetUser.ReturnedTags = new GetUserReq.ReturnedTags();

if (allReturnTags)
{
    getUser.Body.GetUser.ReturnedTags.AssociatedGroups = new GetUserReq.AssociatedGroups();
    getUser.Body.GetUser.ReturnedTags.AssociatedDevices = new GetUserReq.AssociatedDevices();
    getUser.Body.GetUser.ReturnedTags.AssociatedGroups.UserGroup = new GetUserReq.UserGroup() { Name = "", UserRoles = new GetUserReq.UserRoles() };
    getUser.Body.GetUser.ReturnedTags.AssociatedGroups.UserGroup.UserRoles = new GetUserReq.UserRoles() { UserRole = "" };
}

对于嵌套在“信封”中的每个项目，我都需要创建一个新对象，否则该标签的输出xml文件将为空。

有任何方法可以进行迭代并满足我的需要吗？

这些是在其中启动信封的代码段

public class GetUserReq {
[XmlRoot(ElementName = "Envelope", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
        public class Envelope
        {
            [XmlElement(ElementName = "Header", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
            public string Header { get; set; }
            [XmlElement(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
            public Body Body { get; set; }
            [XmlAttribute(AttributeName = "soapenv", Namespace = "http://www.w3.org/2000/xmlns/")]
            public string Soapenv { get; set; }
            [XmlAttribute(AttributeName = "ns", Namespace = "http://www.w3.org/2000/xmlns/")]
            public string Ns { get; set; }
        }

并继续包含其他类的正文

[XmlRoot(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
    public class Body
    {
        [XmlElement(ElementName = "getUser", Namespace = "http://www.cisco.com/AXL/API/9.1")]
        public GetUser GetUser { get; set; }
    }

您仅定义类，而没有这些类的属性。参见下面的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            GetUserReq userReq = new GetUserReq();
            userReq.Envelope = new Envelope();
            GetUserResponse userResponse = new GetUserResponse();
            userResponse.Envelope = new Envelope();
            userReq.Body = new Body();
            userReq.Body.GetUser = new GetUser();
            userReq.Body.GetUser.ReturnedTags = new ReturnedTags();

            Boolean allReturnTags = true;
            if (allReturnTags)
            {
                userReq.Body.GetUser.ReturnedTags.AssociatedGroups = new AssociatedGroups();
                userReq.Body.GetUser.ReturnedTags.AssociatedDevices = new AssociatedDevices();
                userReq.Body.GetUser.ReturnedTags.AssociatedGroups.UserGroup = new UserGroup() { Name = "", UserRoles = new UserRoles() };
                userReq.Body.GetUser.ReturnedTags.AssociatedGroups.UserGroup.UserRoles = new UserRoles() { UserRole = "" };
            }

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            XmlWriter writer = XmlWriter.Create(FILENAME, settings);

            XmlSerializer serializer = new XmlSerializer(typeof(GetUserReq));
            serializer.Serialize(writer, userReq);
        }
    }
    [XmlRoot(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
    public class Body
    {
        [XmlElement(ElementName = "getUser", Namespace = "http://www.cisco.com/AXL/API/9.1")]
        public GetUser GetUser { get; set; }
    }
    public class GetUser
    {
        public ReturnedTags ReturnedTags { get; set; }
    }
    public class ReturnedTags
    {
        public AssociatedGroups AssociatedGroups { get; set; }
        public AssociatedDevices AssociatedDevices { get; set; }
    }
    public class GetUserReq
    {
        public Envelope Envelope { get; set; }
        public Body Body { get; set; }

    }
    public class GetUserResponse
    {
        public Envelope Envelope { get; set; }

    }
    [XmlRoot(ElementName = "Envelope", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
    public class Envelope
    {
        [XmlElement(ElementName = "Header", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
        public string Header { get; set; }
        [XmlElement(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
        public Body Body { get; set; }
        [XmlAttribute(AttributeName = "soapenv", Namespace = "http://www.w3.org/2000/xmlns/")]
        public string Soapenv { get; set; }
        [XmlAttribute(AttributeName = "ns", Namespace = "http://www.w3.org/2000/xmlns/")]
        public string Ns { get; set; }
    }
    public class AssociatedGroups
    {
        public UserGroup UserGroup { get; set; }
    }
    public class AssociatedDevices
    {
    }
    public class UserGroup
    {
        public UserRoles UserRoles { get; set; }
        public string Name { get; set; }
    }
    public class UserRoles
    {
        public string UserRole { get; set; }
    }
}

您可以使用反射。

public object CascadeInitializer(Type type)     
{
    var newObj = Activator.CreateInstance(type); // create new instance of your target class
    Func<PropertyInfo,bool> query = q
        => q.PropertyType.IsClass &&            // Check if property is a class
           q.CanWrite &&                        // Check if property is not readOnly
           q.PropertyType != typeof(string);    // Check if property is not string

    foreach (var el in type.GetProperties().Where(query))
    {
        // create new instance of el cascade
        var elInstance = CascadeInitializer(el.PropertyType);
        el.SetValue(newObj, elInstance);
    }
    return newObj;
}

用法

var x = CascadeInitializer(typeof(Envelope));
